Key features:

✓ Certified protection and compliance: Tested and certified by TÜV, to meet European safety standards, ensuring the same reliability as a conventional breaker with added functionalities.

✓ Different pole configuration and rated currents: Available in four pole configurations, each with rated currents from 10 A to 63 A with C tripping characteristics, covering the majority of one-phase and three-phase breaker needs.

✓ Real-time monitoring with notifications: Continuously monitors circuit voltage in real time and delivers instant push notifications for critical events, including tripping and overvoltage/undervoltage conditions ensuring proactive awareness and rapid response.

✓ Overvoltage & undervoltage protection: Protects downstream equipment by breaking the circuit if the voltage exceeds or falls below the user-set safe limits.

✓ Remote connection & disconnection: Enables safe and convenient remote control for maintenance or emergency situations, such as fire, flooding, or earthquakes, when immediate disconnection is required.

✓ Multiple connectivity options: Includes Wi-Fi, Bluetooth, Ethernet, Bluetooth Gateway, and Wi-Fi range extender for flexible, reliable communication across diverse network setups.

✓ Audit and activity logging: Records every event with timestamp and source, ensuring full traceability.

✓ Custom scripts, actions, and schedules: Create your own advanced automation solutions for any scenario.

✓ No Hub Required: Ready to use locally or remotely via Shelly Smart Control or compatible home automation systems.

 

Automatic Protection Against Electrical Faults​

Prevent damage and hazards by automatically interrupting electrical current during overloads, short circuits protecting the installation and reducing fire risk.

 

Remote Monitoring and Control

Enables users to monitor breaker status and input voltages in real time from anywhere via Wi-Fi, LAN, or cloud services, providing peace of mind and faster response to issues.

Allows remote or scheduled disconnection of power for emergency shutdowns or planned maintenance without physical presence, improving safety and operational flexibility.

 

Timely Fault Notification and Diagnostics

Alerts and logs all on/off events with timestamps and sources (manual, remote, trip), allowing quick identification of faulty circuits and reducing downtime. Facilitate preventive maintenance by providing detailed audit logs and voltage monitoring to detect abnormal conditions before failures occur.
